Earth's largest mass extinction had surprisingly little effect on the range of lifestyles seen on the planet's seafloor, despite the loss of more than 90 percent of marine species, researchers find.
Understanding the impacts of this ancient extinction event may shed light on the damage climate change might now inflict on the planet, the scientists say.
The end-Permian mass extinction, which occurred 252 million years ago, was the biggest die-off in the planet's history, and the largest of the five mass extinctions seen in the fossil record. The cataclysm killed as much as 95 percent of all species on Earth.
